HYBRID EXCAVATOR

摘要

PURPOSE: A hybrid excavator is provided to efficiently use restoring energy by using swing motor and traveling motor generators. CONSTITUTION: A hybrid excavator comprises a motor generator(21), a swing motor generator(27), a traveling motor generator(28), an inverter(26), and a condenser(29). The motor generator is connected to an engine and generates energy. The swing motor generator collects energy generated when the excavator is swung. The traveling motor generator collects energy generated when the excavator is travelled. The inverter controls the swing motor generator and the traveling motor generator. The condenser is electrically connected to the inverter and stores the collected energy.
